To all whom iii-may concern:

Be it known that l, Brennan A. TERRY, a citizen of the United States, residing at Roanoke, in the county of ltoenolie and State of Virginia, have invented a new and useful Oil-Burner, of which the following is a specification.

The presentinvention sppertains to oil and aims to provide a novel and. improved burner adapted to be disposed. Within or projected into the combustion chamber of a boiler furnace, heating furnace, or the like.

The invention contemplates the provision of an oil burner of unique construction, and embodying a novel assemblage of component parts, whereby the utility of the device will. be enhanced.

,With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combi nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed can he made within the scope of What is claimed Without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, I wherein- Figure 1 is a longitudinal sectionol' the improved burner parts being shown in full. Fig. 2 is an end View of {the burner lo0king toward the outlet or nozzle end, and a portion being broken away; Fig. 3 is a sectional detail taken on the line 3+3 of Fig. 53. Fig. 4; is a sectional detail-0f the outlet or nozzle end of the burner, illustrating a modified form of spreader.

In carrying out the present invention, there is provided a cylindrical or tubular casing 1., the bore or passage 2 of which has its rear end contracted slightly, and threaded as at The bore 2 is contracted in diameter adjacent its forward or outlet end, as at i, and is tapered as at 5, nexn inside the contracted or restricted portion 4%. The outlet end of the bore 2 is counten bored or countersunk, as at 6, to provide a rounded or hemispherical socket or at the nozzle oroutlet end of the casing l. lhe said casing provided with a lateral opening or port 7 adjacent the basal or hntt end of the casing l or the threaded opening: 3 thereof. A supply pipe 8 for steam or othee pressure tlnid opening or port '3, to

some longitudinally or axially.

ed or secured upon the stem or threeded into supply steers or other fluid into the here #2: of casing, it being understood the steers. or etomining field through the pipe 8 may be controlled by tiny editable valve (not shown)- fuel or oil nozzle 9 projects forrvcrdly within the casing l; end is of smeller diameter than the said casing the nozzle 9 being provided butt or besel end, with the slightly enlsrg'ed and threaded portion 18 which is threaded into the opening 3 the casing l to maintain the nozzle in axial *or concentric position Within the casin The rear or end of the nozzle 9 is provided with a head. 11 whichseats against the basal or rear end of: the casing l. and the bore or passe e 12 oil the nozzle 9 extends through the heed ii, The forward or free end of the nozzle 9 terminates short of the contracted portion t; of the here 2, and is flared, as at 13, to provide a conical or ta pered valve seat 1% within the forward end or tip of the nozzle 9. The heed 11 or hntt end portion a lateral opening or port 15 leading to the bore 1%, and into which is threaded the dis charge end of the supply pipe 16 for the oil or other liquid fuel which isto be con sinned.

A nipple 17 is threadedinto the rear end of the bore 12 and a valve stem or spindle 18 which projects axially or centrally through the nozzle 9 and casing l is thread ed through the nipple 11?. A gland 19 is threaded upon the outer or rear end of the nipple 17, to compress the packing l0 tightly around the stem. or spindle 18 to prevent leakage. The outer or rear end of the stem or spindle 18 is equipped with e suitable hand wheel rotating the stem or spindle to adjust the 22 is mountspindle l8 in any suitable manner adjacent the free end or tip of the nozzle 9. to cooperate with the seat 14%, there being a'mixing; chamber in advance of the valve and spreader 22 or between the free end of the nozzle 9 and the contracted portion l of the bore 2.

ii. collar or tubular member is mounted upon the stem or spindle 18 within the contracted portion 4*. of the bore :2 and series A conical valve end spreader Ito further restrict the passage or opening of the nozzle 9 is provided witi 21. for convenience in v collar or portion 4. Thus, the tubular member 24, provides a restricted annular outlet for the mixing chamber 23 leading tothesocketor recess through the contracted 6. Pins 25 are engaged through the collar 24 and stem 18. and project from the collar '24 }to provide .fingers' or lugs slidably. en-' gaging the walls of the contracted portion '4;

tofguide the forward end portion ,of the stein 18' for axial or longitudinal movement.

As illustrated in .Figs. 1', 2 and'3, a pc- 1 culiar form of spreading means is mounted within the socket or recess 6'for providing 3 an arcu'ate upwardly-directed flame. This spreading means embodies a stationary re-- movable faceandclosure member 26, which is of approximate lune-shaped contour, and

j which has itsroundedfside or base fitted snugly Within the lower portion of the socket or recess 6 and equipped with a pair of depending lugs or. pins 427 engaged through a pair of apertures or openings 28 formedin the-lower or. bottom portion of Thus, the member 26is removably held in place within the'nozzle end of the casing 1.

the-lower portion of the nozzle of'the cas ing- 1-. The member 26 has one flat side or face arranged fiushwith the forward end of the casing 1,"and its other fiat side or face is disposed parallel with but slightly below the axis of the casing. The forward end of the stem or spindle 18 asses over the memher- 26, and the ends 0 the said member 26 are provided with upturnedguide ears or lugs 29 restin'gagainst the sideportions of the nozzle 01'' forward-end of the casin 1Q A-spreader 30, which is of ap'proxnna'te lune-shape, is disposed within the upper portion of the socket or'r'ecess 6jabove the member 26.; One flat side of thc'spreader 30 is seated upon the upper flat side of the -member 26, while the other flat side of the spreader 30 is normally disposed flush with the forward end of the casing 1. The curved side of the spreader 30 has a slightly shorter radius of curvature than the socket or recess 6, whereby the curved side "of'the spreader will be normally spaced from the upperand side portions of the socket 6' to provide an arcuate outlet slot for the nozzle end of the burner.' The spreader 30 is slidably mounted-[upon the member 26 between the'ears 29, and is mounted upon the for- I ward end of the stem 18 to seat'against the collar'or tubular member 24. A nut or retaming element 31 is threaded or otherwise engaged upon the forward, extremity of the stem 18 to retain the spreader 30in place, .it being observed that the. stem. 18 is rotattably mounted within the spreader. The spreader 30 and seat element or member 26 I are jointly somewhat in the formof a hemisphere, the member 26 (:lOSI gthe lower portion of the outlet through the socket 6.

A second spreading means is illustrated in tracted portion 4 of forward end portion of the stem 18 in proper ployed with the 2e-30. Thus, moved and the from the socket when the spreader 3035' reseat element 26 withdrawn 6, a-hemi-spherical spreader 9, when the stem 18 is t readed or adjusted forwardly, the valve or spreader 22 will be forced away from .the 'seat 14 and the gspreader 30 or-32, which ever is employed,

gopening or contracted portion 4 of the bore 2. The steamer atomizing fluid in passing j the flared end 13 of the nozzle 9 and being around the annular base or slot between'the valve 22 and the seat 14'to' thereby draw the oughly mixed, under the agitating action of the atomizing r pressure fluid and the mixture is then discharged through the nozzle thestem 18/- is threadcd'or adjusted rearwai'dly, the valve or spreader 22.n1ay be ;brought tightly against the seat 14, and the spreader or 32 drawn inwardly to close vthe ou-tle opening 4, so that the outlet or oil will be stopped or checked. Should the I burnerbecome the sediment or foreign matter m ay be ejected by threading the considerable extent, whereby the pressure matter.

The pins 25 carried by the stem 18 and en gaging the walls of the opening or conthe bore 2 will hold the position, and thereby properly hold the valve J and spreader 22 in cooperative relation with the 'seat 14.- of the nozzle 9, and to hold the spreader 30 or 32 improper operative position.

nection' with the seat element 26, the spreader 30 will be adjusted longitudinally upon the seat element 26 when the stem :18
